' UNITED- STATE S-"PATENT OFFICE This invention relates to a printing machine. More'particularly, this application is a continuation in part of my'application Serial No. 164,726, filed September20, 1937, which has matured into Patent No. 2,224,886, December 1'1, 1940.

' While in this application I shall. showand describe a number of features .which are divided 'from my earlier-application, several of these features will be shownin physical embodiments somewhat different from those of my earlier application. This is due to the fact that since tlling my application supra, I have been continuously developing and improving the structure thereohas will be appreciated'by those skilled in the art. Moreover, I shall in this application make claim to certain basic features which are shown in 'my earlier application,- but are not therein emphasized nor claimed.

The printing machine of my invention has the same general arrangement as the printing ma chine of my\earlier application in that it utilizes a reciprocatin bed and a rotatable cylinder op-' erable relatively to that bed. .A basic and important feature of the machine is the arrangement of the bed and its bed bearing relatively to the impresion cylinder so that the bed is fully exposed onits hearing when at the end of its printing stroke, whereby the chase thereon is readily available for operation by the printer, as

may be reduired'for'the setting of type. etc. In

addition, this presents a large area .over which my inkingassemblymay be placed.

The paper feed mechanism of my machine is at that end of the machine to which the bed moves in its return stroke,- portions of the paper,

. This feature comprises the feeding of the paper from'the feedrack to a point tangential with the under portion of the periphery of theimpression cylinder. so that the paper may be carried 7 about and over the impression cylinder, and then moved rearwardly towards the delivery rack in a line parallel to the line in which the paper is fed to the cylinder, but superimposed thereoven.

the several advantages of this'particular feature, It is interesting to note that this arrangement makes it possible to utilize asingle pair of side guides for both the feed and delivery racks, with said guides capable of simultaneous adjustment to the width of the paper sheets, without the need for complicated controls. I

As a further feature of my invention, I arrange for the cylinder to be" rotated by the bed through flexible cables connected between the cylinder and bed in a novel and unique manner. This novel drive arrangement contributes many advantages, and is especially 'eflective for permitting the upward and downward movement of the impression cylinder relatively to the bed, that is, the movement of the cylinder intoand out of the printing plane. This movement of the cylinderinto and.out of the printing plane is controlled by the reciprocating bed,- it being the function of the bed to move the cylinder into the printing plane for the printing stroke, and to move the cylinder out of the printing plane for the reverse stroke of the bed, and also under certain emergency conditions, such as when there 25 is no paper to be fed, and in .the event the paper is being fed in'an improper manner. For thus controlling the cylinder, 1 utilize a novel type of v feeler. and control mechanism including as its salient feature a feeler which is operable by a der, which is of extreme importance, is the feareverse or feed stroke.

ture-whereby thecylinder is driven through suitable clutch means only when the bed is moving through its printing stroke, the cylinder. remain ing at rest whenfthe ibedis moving through its It is therefore possible to feed the paper to the cylinder when the cylinder is stationary, at which time the grippers on the cylinder are arranged to be open and ready to accept the paper. In this manner, extremely accurate end register is obtained. Moreover, a very simple type of gripper mechanism may be As a further feature of this phase of my in.-

vention, I utilizethe up and down movement of the cylinder to actuate the clutch mechanism between the'cylinder. and the bed. This up and Those skilled in the art-will readily appreciate down movement of the cylinder is further utilized carried by the bed. 1

for controlling the grippers and other means, all as will be set forth hereinafter; A further feature of the invention is the utilization of the up and down movement of the cylinder for controlling paper feed means other than the grippers for feeding the paper from the cylinder toward the deliveryrack. Y

A further feature of my, invention is provide in the novel type of beltutilized for feeding the paper from the feed rack toward'the machine; The novel belt of my invention is in the form of a metal link belt to which may be secured in a very novel manner, a series of feed elements, all

as will be hereinafter set forth in detail. My

belt is mounted so that it is readily counter balanced, the counter balancing means being utilized also for controlling the paper feed where- .by to maintain the paper on the feed rack at a invention utilizes a spring finger for contributing:

side register. all as will be explained hereinafter. A still further feature of my invention which is, of extreme importance is what I terma caliper gap separatorwhich I have conceived and dey veloped, and which contributes not only a caliper gap operation, but functions as a separator as well. Thus, when several "sheets of paper are presented to my caliper gap, one of the said sheets jwlll bejallowed -to pass through the gap, while the remaining sheets will merely move portions of the gap out of obstructing relation so that there will benojamming of the ntire group of sheets approaching the gap. This arrangement will be;.set forth in detail in the specification which follows, and will be claimed broadly. I shall also lay considerable emphasis on the cooperation with my caliper gap separator, of means utilized for'fanning the several sheets, as well as the angular stacking of the sheets of paper on the feed rack.

"Ai'urther feature of the invention is the arrangement whereby the ink assembly is driven directly by the impression cylinder so as to efiect that the detailed description which follows ma be better understood. Naturally, I have not described generally all of the features of my new and novel printing machine, since many of those features will best be understood when their detailed descriptions are presented hereinafter. I

should like to have it understood that those skilled in the art will readily conceive that the features of'my invention may be incorporated in physical embodiments other than those shown. Therefore, I shall expect to obtain a monopoly of suflicient breadth to prevent the utilization of my contribution in such other forms as may readily suggest themselves to those skilled in the art.

Fig. 21s a vertical section through my machine showing the several operating parts thereof. Fig. 3 is an end view of Fig. 2 showing 'parts of the paper feeding mechanism. Fig. 4 is a. section taken along lines 4-4 of Fig. 3. Fig.

Fig. 5a is a-view of the underside of the feed belt, while Fig. 5b'is a section along lines lib-5b of Fig. 511. Fig. 6 is a s'ectiontaken along lines 6'6 of Fig. 2. Fig. 6a is. a perspective view showing the relationship of the various paper. guides utilized in a continuous" drag on the operational the rollers 1 of the ink assembly during the printing stroke.

This, as will'b appreciated, prevents back lash between the several parts, and especially between the cylinder and the bed, when there are gaps between cuts or other copy in the printing form. Those skilled in the art-will appreciate that this arrangement makes it unnecessary to utilize the friction means which are normally required in prior art machines for maintaining the impression cylinder in proper timing relation to the bed. As stilla further feature of my machine, the inking assembly is so arranged relatively to the cylinder and the bed that the form rollers thereof are capable of'vertical' movement relatively to the bed and out of the plane of the type on the .bed, making it possible to utilize mimeograph and inking ribbon units as part of the chase I have thus described generally a number of the features of my machine in order that a proper ',appreciat ion thereof may be had, and in order my machine.
